We have Exchange 2003 servers across our organisation, We would like to monitor the mail traffic. 1) Internal Mails (between our own exchange servers) 2) Incoming mail from Internet to our domain 3) from our domain to other domain (out going). Can anyone help me... Thanks in Advance. Gnanavel

Have a look at MOM or a 3rd party monitoring solution. MOM comes with an Exchange Management Pack that allows you to monitor traffic flows, service availability, queues, services, etc. Tony www.activedir.org
